Ive not changed the set up since October 2011, And I do not reconize any emails on the list besides registration@ebay.com but thats a generic one. The IP address which i think sent it was the 212.156.182.55 which is in turkey. My server is hosted in Manchester UK

In that case, it suggests as if you're being used as a relay despite testing... what service did you use to test for it? mailradar.com/openrelay I assume the server is free of virus's etc and it's not a script on the actual server sending it out?

All tested completed! No relays accepted by remote host! is the result of that. Server as far as im aware is and no automatic emails are sent from that server
